Which finish is typically avoided when aiming for a classic London-type stock finish?

In the context of achieving a classic London-type stock finish, industrial varnish is typically avoided because it tends to create a more modern, glossy appearance that does not align with the traditional aesthetics of classic finishes. London-type finishes often prioritize a natural look that showcases the wood grain while providing some level of protection without overwhelming the visual beauty of the wood.

Oil finishes and shellac are more in line with traditional practices, as they enhance the wood's character, depth, and color without forming a thick layer on top, which could detract from the charm of the wood. Waterproof coatings are also avoided in this context, as they may create an unrealistically high sheen and are often more suited for utilitarian applications rather than the refined look associated with classic stock finishes. Thus, industrial varnish stands out as the choice that does not fit the desired classic aesthetic.
